3 Claims.

This invention relates to hinges, and more particularly to shielded hinges. y

The object of this invention is to provide a shielded hinge which may be easily inserted into a door without the necessity of complicated boring, insertion of screws and the like.

For this purpose the invention consists o-f a. shielding casing having a bifurcated slot therein for the passage of a stem engaging a cylindrical portion so that upon the ascent anddescent of the door, as is customary with hinges of this type, the parts are concealed as much as possible. y

The invention will be more fully described hereinafter, embodiments thereof pointed out in the drawings, and the invention will be inally set forth in the claims.

In the accompanying drawings:

Figure 1 is a partial side View o-f a door and door casing with the improved. hinge applied thereto;

Figure 2 is a section taken on ure 1; v

Figure 3 is a horizontal section taken o-n line 3-3 of Figure l;

Figure 7 is a side view showing the detail of the cam stem;

Figure 8 is a top view of Figure 7;y and Figure 9 is a sectional end View of the casing, taken on the line 9-9 of Figure 6.

Similar characters of reference indicate corresponding parts throughout the various views.

Referring to the drawings, -andmore particularly to Figure 1, the usual door casing I0 has supported thereon a door II by means of the hinges generally indicated by I2 and I.` It is a desire in hinges of this kind to have the exterior casing made of chrome plated metal, and preferably to have it of continuous contour, i. e., shielded or the like, so that a barrel casing of the hinge from the exterior appears the same no matter in what position the hinge is placed. For instance, the casing of the hinge I3 is cylindrical and chrome plated at its exterior and makes a very pleasing appearance, and in consequence it is the desire of users of hinges to have the upper hinge I2 present substantially the same appearance. It has heretofore been proposed to have line 2--2 of Fig- (C1.v Iii-153) thecasing of the upper hinge of one uniform metal cylinder, i. e., shielded, but it has been found that when. devices of thatY kind were applied to the door it was necessary to cut out from the top of the door recesses in the door structure and bores inthe door itself toenable screws to pass through, which screws were to hold the improved hinge. Other deficiencies of installatio-n are attendant that type of hinge.

This invention overcomes these objections by reason of the fact that a short .distance below the top of the door a simple recess is cut out as indicated by the line I5 in Figure 6; and into this recess there is then inserted the internal cylinder I 6 and the external cylinder Il. The eX- ternal cylinder Il has two rearwardly extending flanges I8 and I9 having openings 2U therein in registration with each other, and screws 2| and.A 22 are then inserted past these openings 2B so as to enter the sleeve 23 of the bore 24 of the door I-I. When these screws are thus inserted to engage into the openings 25 of these rearwardly extending. ears I8 and- I9, the internalV cylinder I6 and external cylinder I'I are held in position in the recess I5 of the door. The fastening to the door casing is equally simple, in that an L-shaped member 25 has an opening 26, and this L-shaped member 25 has a cutout 2l in which is seated an extending portion 28 of a member 29 having a bore 30. Screws 3| and 32 pass through the openings 26 and 30, and entering the sleeve 34 which is seated in the bore 35, secure these plates 25 and 29 in position. To the plate 25 is secured a stem 36 which basan annulus 3l, in the opening 38 of which the vertical shaft member 4!) enters. The shaft member 4I) as shown in Figure 5 is made integral with a disc member 4I having an inset portion 42 of concentric circumference, and upon the inset portion 42 the internal cylinder I6 is seated, whichy internal cylinder I5 has the opening 43 for the passage of the stem 36. The; door II when moved on its hinges causes y the shaft 4I! to rotate within the annulus 31, but as the door raises itself it is necessary for the outer ycasing Il to have an inclined slot which is indicated in Figure 1 by the character 55 and extends from the inside of the door downwardly on both sides thereof. Thus, as the door I I swings and is raised, the exterior cylinder I'l has the upper part of its slot right upon the stem 36, and when the door is moved in the opposite direction, the same ascent takes place and the upper wall forming the upper part of the slot rides upon the stem 35 until the movement of the door i5` is limited by the extreme end of the slot indicated by 5I.

It will thus be seen that the exterior cylinder I1 at the exterior thereof is of a smooth surface appearance such as shown in Figure 1, and appears to be an entire and uncut cylinder save only for the slot 58. The walls I1 of the external cylinder forming this slot are curved as shown in dotted lines in Figure 6 at 52, and thereby present a very pleasing appearance, such grooving or beveling adding to the effect of the hinge. The external cylinder I1 at the edge of the door facing the door casing is slightly pointed at the slot portion at the lower part of the slot, and has a slight curvature at the upper part of the slot acting as a seat which rests upon the stern 36. The formation of this seat serves to hold the door in neutral position, i. e., in alignment with the door casing. Thus when the door is moved the cylinder may be moved to that position Where the exterior end ofthe slot engages the stem 36, at which point the door takes a position at right angles to the door casing. y

It will thus be seen that a very agreeable looking device has been produced by means of the mechanism proposed, namely, the inner base member 4I with its shaft 48 being secured to the external cylinder I1, said shaft member being surrounded by the annulus 31 having the opening 38, the annulus 31 being held by the stem 36 to the ears 25 and 29 secured to the door casing. The internal cylinder I6 is freely rotatable within the cylinder I1 and has a vertical slot 50a. for the stem 36. The cylinder I6 serves to close all parts of the slot which are not occupied by the stem portion 36. Thereby, a shielded hinge is obtained permitting vertical and horizontal rotary movements.

As before stated, a device of the kind described may be readily inserted in a door by merely cutting out a recess I5, and then applying the the door I I at the bottom edge of the door.

ears to the'door by mea-ns of screws, such as 2I, 22, 3| and 32.

It will be noted that the improved hinge forming the basis of this invention is applied near the top of the door, and the other hinge at I3 is likewise applied at the bottom of the door.

The other hinge will be briefly described for the sake of completeness, but forms no part of this invention, it being well know-n.

As shown in Figure 6, a cylindrical hollow casing 6U has a displaceable cap 6I held thereon by screws 62, and has a lug portion 63 having openings for the passage of screws 64 by means of which the hinge I3 can be readily applied to The door is provided with a cutout or recess 65 into which seats a hub portion 66 which is made integral with the cylindrical casing 68. Within the casing 60 there is a centrally disposed shaft 68 shown in Figure 7 which has secured thereto a cam member 69 having an inclined cam surface 10. This shaft has a screw threaded lower end 1I which passes through the supporting ear 13 shown in Figure 6, this lower end 1I and ear 13 being locked together with a nut and washer 13a, and which supporting ear 13 is held by two parallel members 14 and 15, shown in Figure 3, to the door casing I0 by means of the screws 16 and 11. These members are again formed in the same manner as the members 25 and 29, the member 14 being L-shaped, having a recess 18 into which a depending flange 19 ofthe member 15 fits. The lower end of the shaft 68 is knurled, as indicated by in Figure 7, so as to have this knurled portion engage the seat 8| of the ear 13, as shown in Figure 6, in such a manner that there is no relative rotation between the parts. A roller 82 is provided within the casing 68, which seats upon a shaft stem 83 so that the roller can rotate in respect thereto, the shaft stem 83 having the screw threaded end 84 seated Within the screw threaded bore 85 of a central shaft 86 which has its subcaliber stem 81 knurled at its exterior so as to engage within the hub 66, the lower part of the shaft below 86 being free of but fitting within the hollow shaft 68 and also inside of the cam member 69.

4 Thus, as thel door is moved, the shaft 86 is moved thereby, and this movement is in turn transmitted to the roller 82 carried by the shaft 86. The roller 82v rests in a correspondingly shaped groove of the cam member surface at 90, and by a frictional action causes the roller 82 to revolvej and ride upward upon the grooved cam member surface vat 10 and towards the top 9`I thereof, vdepending upon the extent to which the door is opened. This roller 82, being iixedly secured to the casing 60 and to the door, but beingfree of the cam member 69 and shaft 68 which are iixedly attached to the casing I D, causes the casing60 with the door attached to raise itself, the shaft 68 remaining permanently stationary, being iixedly attached to the casing I 8 by the supporting ear 13 and the parallel members 14 and 15. Similarly if the movement takes place in the opposite direction. After the door has been vraised in either direction, gravity action upon the door causes it to descend along the cam member 18 and returns the door to its initial position, it being held by the rear portion 58a of the Vslot 50 of the upper hinge, as shown in Figure9, and bythe resting of the roller-82 in the groove of the surface cam member 69 at 98 in the lower hinge.

It is obviousthat various changes and modiiications may be made in the vdetails of construction and design of the above specifically described embodiments of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scopeof the following claims.

-What is claimed is:

1. In a swinging door hinge, a leaf adapted to be secured to a door casing, a stem on said leaf, an exterior cylinder mounted on a swinging door, said cylinder having a bifurcated` slot therein vfor the passage of said stem, an inner cylinder coaxial with said exterior cylinder and having aslot for the passage of said stem, a vertical pintle mounted in said cylinders, and an annulus on the free end of said stem embracing said pintle, the inner cylinder` being rotatable within the exterior cylinder to close all that portion of the bifurcated slot adjacent the sides of said stem.

2. In a swinging door hinge, a cylindrical member adapted to be secured to and be movable with a swinging door, and having a slot inclined to the horizontal and a central pintle for said member, combined'with an interior cylindrical member having a vertical slot and adapted to be seated within the first cylinder, and rotatable in respect thereto, and a stem adapted to be secured to the door casing and having means engaging said pintle, said stem passing through both of the slots.
